With over 25 years of experience as an educator and more than 15 years in leadership, Dr. Guppy has consistently advanced academic excellence and organizational growth. Her leadership has included guiding teams, programmes, and educational initiatives, as well as establishing effective processes, organizational structures, and policy frameworks at both departmental and university levels. She excel at engaging with staff and students alike, promoting collaboration, trust, and a shared commitment to success. Dr. Guppy is a proactive and diligent professional with strong critical thinking, analytical, and communication skills. Her career reflects a proven ability to deliver thorough project support, combining research expertise with organizational efficiency. As an experienced researcher, she focuses on advancing scientific knowledge through meticulous data collection, analysis, and collaboration. she brings extensive expertise in marine environmental health, molecular biology, and ecotoxicology, and excel in both field and laboratory settings. Her strengths include conceptual thinking, conducting comprehensive literature reviews, and working effectively with multidisciplinary teams to drive impactful research outcomes.
Dr. Reia Guppy is an Associate Professor at The University of Trinidad and Tobago (UTT), with overall interest in marine and coastal environmental health, population connectivity, and genetic resilience. Since 1996, Dr. Guppy has contributed to and participated in coastal and marine biological and ecological surveys around the world. Over the years, whilst her primary research was focussed on coral reef health and disease, she has more recently been targeting research revolving around (1) the effects of climate change on ecosystem resilience, (2) genetic resilience of key organisms (mangroves, corals, conch, caiman, manatees, scarlet ibis), (3) bioindicators of pollution, (3) population and community biogeography and niche capacity, and (4) environmental forensics.
Throughout her career, Dr. Guppy participated in eight environmental impact assessments, and supervised over 50 student projects on topics such as biodiversity, pollution, toxicology, and climate change. Over the last few years, Dr. Guppy has also been contributing on a national level, notably: (1) the building biodiversity and conservation of natural resources through participation in initiatives such as the advancement of the Nagoya Protocol in the Caribbean region; (2) legislative perspectives and framework for Nagoya and ABS; (3) building capacity for a national biodiversity information system; and (4) national consultation for CARICOM Environmental and Natural Resources Policy and Draft Environment Action Plan. She has worked with organizations such as the Turtle Village Trust to study the changes in population dynamics, and the effects of climate change on hatchling success. From this work, she is a member of the National Sea Turtle Task Force.
Regionally, she has worked alongside Canbean Associates to mainstream environmental information management and multilateral environmental agreements (MEA) objectives to increase St. Lucia’s capacity to monitor MEA implementation and sustainable development. Currently, Dr. Guppy is engaged with CANARI on conducting a national ecosystem assessment of Grenada. Additionally, she is involved with the LIFE Adapt'Islands Project in Guadeloupe, with the objectives to make the territory better adapted to climate change and to build its resilience against extreme climate events. Internationally, Dr. Guppy represented Trinidad and Tobago at the Ocean Acidification SIDS conference in Apia, Somoa
She attained her PhD from Newcastle University in the UK in 2006, and in 2009, Dr. Guppy joined UTT and was instrumental in the development of the first dedicated Marine Sciences department in her country. To date, she has lead the successful implementation of bachelor, master, and MPhil/PhD degrees devoted to the coastal and marine environment. More recently, Dr. Guppy has made efforts to contribute towards environmental forensics. She completed her MSc in Pharmacology with a specialization in Forensic Sciences in 2019.
Through this, she marries her expertise in marine biology/ecology, toxicology and connectivity towards organismal resilience, protection and conservation. With 25 years of national, regional and international experience, Dr. Guppy’s unique background provides a unique blend of expertise suitable for determining the current and future status of a wide array of organisms, particularly in response to climate change and pollution. Her involvement with the Governmental and regional level stakeholders, along with her international experiences, allows her to the ability to positively contribute towards much needed biodiversity and environmental policy frameworks and forecasting.
